More than 20 years ago, climate scientists began to raise alarms over the possibility global temperatures were rising due to human activities, such as deforestation and the burning of fossil fuels.

To better understand this potential threat, the World Meteorological Organization and the United Nations created the Intergovernmental Panel on Climate Change (IPCC) in 1988 to provide a "comprehensive, objective, scientific, technical and socioeconomic assessment of human-caused climate change, its potential impacts and options for adaptation and mitigation."

IPCC reports have predicted average world temperatures will increase dramatically, leading to the spread of tropical diseases, severe drought, the rapid melting of the world's glaciers and ice caps, and rising sea levels. However, several assessments of the IPCC's work have shown the techniques and methods used to derive its climate predictions are fundamentally flawed.
